Exception29 when interface is disconnected

[s0170071]

it was all running smoothly until I disconnected the cable and forgot to re-connect it. After a while it crashed. Looks like a simple queue overflow to me ;-) I had 60 datapoints queried at an interval of 10s, so the queue was filling up pretty quick. I suggest to limit the queue size to the amount of added data points.

Exception (29):

queue size limitation is indeed a to do. I was thinking of twice the number of datapoints to leave room for writing while a readall command is started.

should be solved in V1 branch
